U'NITED STATES Parser orri'e ODIN HENRY WILSON, OF. CEDAR VALE, KANSAS.:

Application filed September A all'whom it may concern:

Be itknown that I, OLINH". WV'rL'soN, a citizen'of'theUnited Stat'es,and a resident of Cedar Vale,,in the county of Chautauqua and State ofKansas, have invented certain new and usefullmprovements in Cut Outs,-.of which the following is a specificae tion.-

inventionrelates to exhaust release devices especially adaptedffor useon internal'fcombustion engines.

Briefly. stated an important object of. this invention is to providean*- exhaust release device. having simple means, whereby the same may.be opened'to permit of the. free and unobstructed movement of theexhaust gases to the atmosphere without the necessity of first travelingthrough the mulil'er and without the necessity of" making objectionablebends.v

A further object of' the invention is to provide simple means wherebythe improved cut out. device may be incorporated in. anexhaust lineeither duringthe manufacture:or assembly of an automobile or at any timethereafter without inconveniencev or the exercise. of unusual skill.

A-further objecti's. to provide a cut out device which is, of. highlysimplified construction,v durable in; use and cheap to manufac-ture.

Other objects and advantages will be apparent during the course of the,following description.

In the accompanying. drawing forming a part ofthis application and inwhich like numerals are employed to designate like parts throughout thesame:

Figure 1 is a. perspective of the improved cuteout device applied;

Figure 2 is a vertical transverse sectional.

viewthrough the improved: cut out device applied;

Figure 3 is a vertical transverse sectional haust-pipefrom the forwardportion of theexhaustpipe: the' said rear portion of the pipe-may be;designated the 'muiliei pi-pe+ In carrying out the invention I provideco -act-ing disleshaped sections 11 and 12,

havin their oaaosedsides flatl' in abutment' and provided wit-h lugsorearsv lg and 14, respectively, for thereceptionyof a bolt 16" by meansof which the; disksor plates are hingedly connected.

The exhaust line- 5 and consequently the section 11 which is rigidlysecured thereto are relatively stationary since the exhaust line issupported by abracket 18 secured to any stationarypart'. of" thevehicle,- such" as the frame by means of a fastening device 20. Theco-actirig sections 11 and 12am formed with openings 22 and: 23 adaptedforregistration so asto establish communication between the'exhaustpipefr and the muflier pipe 9; It willbe seenthat the-exhaust conductingmembers 5 and 9 extend through bosses 25 and 26 and are rigidly securedthereto by set" screws and 28 or other suitable fastening devices;

The disk-shaped member 12which is the main movable member of thestructure is limlted 1n lts movement in one direction by means of anarcuate stopan'd guideflange- 30 integral with andv extending acrosst-helower portion of the section 11 after the manner ofa chord but locatedin spaced relation to the flat face of the section-11. \Vith referenceto Figure 2 it will beseen that the inner surface of the flange 32 isinclined'or beveled'soas to forma' gradually narrowing groove 01:channel" for the reception of the bevel'edlower edge of the movable.section 12. It is. thus seen that when the movable section returns toits normal position with the open'ngs and in registration thebeveledlower edge of the movable section will be engaged with thebeveled inner side of the flange 30 so that the opposed flat faces ofthe sections 11 and 12 will be urged into practically gas tightconnection with each other. In this manner the escape of the exhaustgases between the sections 11 and 12 is prevented. Therefore, the flange30 not only serves asa means to limit the movement of the section 12 inone direction but also as a means to insure a practically gas tightconnection between the disk-shaped members 11 and '12.

The movable section 12 is provided with V a radial arm 36 havingconnection with a coiled spring 37 by means of which the openings 22 and23 are urged into registration. One end of the coiled spring 87 maybe-anchored to a stationary portion IO of the vehicle.

The section 12-may be swung on itspivot by a foot pedalconnected to acable L6 and when the cable 46 is operated the section 12 of the disk 12scrapes away any'dust, dirt,

grease, oil or the like that may have been deposited on the flat face ofthe disk 11' and the edge of the disk 11 likewise'scrapes'the flat faceof the disk 12 to maintain the contacting faces clean and smooth.

However, when the sections are not in registration or are in position asillustrated 'in' dotted lines in Figure 3 the products of coinbustionwill exhaust freely out of the exposed end of the exhaust pipe 5. Itwill be seen that when the cut out is opened the products of combustiondo not have to make sharp bends or turns at the cut out'and consequentlycarbon deposits in the cut out are reduced to a minimum and movement ofthe products of combustion is not in any way obstructednor retarded. I

In order to provide for the escape of'the exhaust gases at all times andespecially during the swinging movement of the section 12, this section12 is provided witha series of concentric arcuate openings 40 located inthe portion of the section 12 that traverses the opening 22. Theopenings 40 are of the cross sectional form shown in Figure a so thatthe strength of'the section 12 will be preserved while the escape of thegases is facilitated.

The invention forming the subject-matter of this application may beincorporated in 7 an exhaust pipe at any time without the exercise ofunusual skill or without elaborately changing the construction of thevehicle.

In the form of the invention illustrated in Figure 4 the sections and 61may be provided adj aoent the cut-out with bends 66 and 67 so that whenthe sections are outof registration the products of combustion will bedirected downwardly toward the ground so as to reduce the fire hazard toa minimum.

Figure 2 illustrates that the section 9 has one end flared or enlargedas indicated at '73, and received within a socket 75in one end of themuffler. A suitable strap or clamp 7 6 may be secured about the socket 75v so as to hold the enlarged or sphere-shaped portion 7 3 within thesocket.

I claim a l. A cut-out comprising co-acting diskshaped sections havingtheir opposed sides flatly in contact and provided with openings adaptedfor registration, means pivotally connecting the disk-shaped sections,one of the sections being provided with a combined stop and guide flangeextending in spaced relation across its face and arranged in the path oftravel of the other disk-shaped section, spring means urging theopenings in the disk-shaped sectionsinto registration, an exhaustconducting member connected to one of 'the' disk-shaped sections andhaving means whereby the same may be universally connected to a muffler.

2. The combination of an exhaust line d1- vided' into two sections, apair of cor-acting disks having their opposed faces flatly in contactand having their outer sides rigidly connected to said sections, one ofthe sections being stationaryiand the other being mov- -able,,a inuflierhaving universal connection with the movable section of the exhaustline, i

and means-whereby to limit the movement of one OfStIld disks withrelation to the 8. In a cut-out, a stationary diskand a movable diskpivotally connected to the sta tionary disk, said disks having centralopeningsadapted for registration, said movable disk having a series ofconcentric arcuate o enin svin the ortion of the movable disk thattraverses the central opening of thestationary disk, said arcuateopenings being" tapered in cross section.

4;. In a cut out, a stationary disk and a movable disk pivotallyconnected to the stationary disk, said disks having central openingsadapted for registration, said movable disk having a series of openingsin the portion" of the movable disk that traverses the central openingof the stationary disk;
